      • TermOrdValComparator

        public TermOrdValComparator​(int numHits,
                                    String field,
                                    boolean sortMissingLast,
                                    boolean reverse,
                                    Pruning pruning)
        Creates this, with control over how missing values are sorted. Pass sortMissingLast=true to put missing values at the end.
    • Method Detail

      • disableSkipping

        public void disableSkipping()
        Description copied from class: FieldComparator
        Informs the comparator that the skipping of documents should be disabled. This function is called by TopFieldCollector in cases when the skipping functionality should not be applied or not necessary. An example could be when search sort is a part of the index sort, and can be already efficiently handled by TopFieldCollector, and doing extra work for skipping in the comparator is redundant.

      • setSingleSort

        public void setSingleSort()
        Description copied from class: FieldComparator
        Informs the comparator that sort is done on this single field. This is useful to enable some optimizations for skipping non-competitive documents.

      • compare

        public int compare​(int slot1,
                           int slot2)
        Description copied from class: FieldComparator
        Compare hit at slot1 with hit at slot2.
        Specified by:
        compare in class FieldComparator<BytesRef>
        slot1 - first slot to compare
        slot2 - second slot to compare
        any N < 0 if slot2's value is sorted after slot1, any N > 0 if the slot2's value is sorted before slot1 and 0 if they are equal
      • compareValues

        public int compareValues​(BytesRef val1,
                                 BytesRef val2)
        Description copied from class: FieldComparator
        Returns a negative integer if first is less than second, 0 if they are equal and a positive integer otherwise. Default impl to assume the type implements Comparable and invoke .compareTo; be sure to override this method if your FieldComparator's type isn't a Comparable or if your values may sometimes be null
